Why each option
Cisco Jabber uses XMPP (Extensible Messaging and Presence Protocol) for its chat and instant messaging features, regardless of whether it is operating in softphone or desk phone control mode.
CTIQBE (Computer Telephony Integration Quick Buffer Encoding) is used by Jabber for CTI-based desk phone control signaling, not for chat or messaging features.
HTTP is used for Jabber service discovery and configuration retrieval, not as the primary protocol for ongoing chat messaging.
XMPP is the underlying protocol Cisco Jabber uses for all chat, instant messaging, and presence functionality, communicating with Cisco Unified Communications Manager IM and Presence Service (or Webex). This protocol handles message delivery, buddy lists, and availability status independently from call control mode. Desk phone control mode changes how audio calls are handled but does not affect the XMPP-based messaging stack.
SIP/SIMPLE is an alternative presence and messaging protocol used by some SIP-native clients, but Cisco Jabber relies on XMPP for its chat engine rather than SIP/SIMPLE.
